![]() Putting the findings in the right perspective and listening to the patients’ symptoms is key.” “If your doctor suspects a NET, further evaluation including blood tests, urine tests, imaging tests and biopsy can be performed to confirm the diagnosis. “The key to accurate diagnosis of NETs is having a complete picture of the patient’s symptoms,” Dr. Flushing (redness of the neck and face)ĭue to the lack of a screening test to detect NETs, it is very important to tell your doctor about the specific symptoms that you are experiencing.Because NETs are perceived to be uncommon and may be nonspecific in their presentation, delays in diagnosis and misdiagnosis are frequent.” What symptoms should prompt a visit to the doctor? But functional NETs cause clinical symptoms due to excess hormone secretion by the tumor. “They may produce symptoms caused by physical compression from the tumor's growth. “Nonfunctional NETs do not secrete hormones,” Dr. Different types of neuroendocrine tumors cause different symptoms, depending on their location and whether the tumor secretes hormones and which hormones. When symptoms do occur, they can be similar to those of other common medical conditions. NETs often don’t cause symptoms early in the disease. Other less common areas include the thyroid, parathyroid, adrenal and pituitary glands. Neuroendocrine cells can be found throughout the body, but they are mainly in the gastrointestinal tract such as the pancreas, appendix, small intestine and rectum, the lungs and thymus. Neuroendocrine cells as the name suggests, receive signals from your brain like nerve cells and can make hormones like endocrine cells. In fact, about half are not properly diagnosed until later stages, when the cancer has spread to other areas and is far more difficult to treat, says Renuka Iyer, MD, a medical oncologist, NET expert and the Section Chief for Gastrointestinal Oncology at Roswell Park Comprehensive Cancer Center. Results of the third study were published in the May 2016 issue of the Journal of Nuclear Medicine, and are the subject of an article published in the Applied Radiology Newsletter and posted online here.Neuroendocrine tumors (NETs) are uncommon cancers that are commonly misdiagnosed as another condition causing delays in diagnosis and care. ![]() The third demonstrated the safety and efficacy of the tracer for the diagnosis, staging, and treatment management of neuroendocrine tumors. The second evaluated 68Ga-Dotatate images using histopathology. The first compared 68Ga-Dotatate images of neuroendocrine tumors to images obtained with an approved drug, and then confirmed with CT or MRI. In its press release, the FDA referenced the three studies that established the safety and effectiveness of NETSPOT, all headed by researchers at Vanderbilt University Medical Center in Nashville, TN. It is currently approved for use with the GalliaPharm® Ga 68 generator from Eckert & Ziegler. An orphan drug is defined as a drug that treat diseases or conditions that affect 200,000 or fewer individuals in the United States or 5 out of 100,000 in the European Union.Īdvanced Accelerator Applications has announced that NETSPOT will be supplied in the United States by Cardinal Health of Dublin, OH, a healthcare services company operating the largest radiopharmaceutical network in the nation. Gallium 68Ga-Dotatate received Orphan Drug Designation in March 2014 from both the FDA and the European Medicines Agency. The uptake of 68Ga-Dotatate reflects the level of somatostatin receptor density in neuroendocrine tumors. 68Ga-Dotatate, a positron emitting analogue of somatostatin, works by binding to such receptors. Neuroendocrine tumors have receptors for somatostatin, a hormone that regulates the endocrine system. The tumors develop in the hormone-producing cells of the body’s neuroendocrine system, and are located in organs such as the stomach, intestines, pancreas, and lungs. Neuroendocrine tumors are malignant and benign tumors that affect an estimated 47,300 individuals in Europe and the United States each year. The commercial product, a single dose kit for the preparation of a 68Ga-Dotatate injection manufactured by Advanced Accelerator Applications of Saint Genis-Pouilly, France, has been given the market name NETSPOT ™. Food and Drug Administration (FDA) approved the use of gallium 68Ga-Dotatate, a radioactive diagnostic agent for positron emission tomography (PET) imaging to locate somostatin receptor positive neuroendocrine tumors in adult and pediatric patients.
